Actually, Dan Silva author of Dpaint, at a recent BADGE meeting indicated
that there were a few bugs in lo-res interlace mode. His explanation was
that he never checked it because he didn't think anyone would use it.
Needless to say many people have tried to use it because using interlace
mode in V1.1 is the only way to prevent the frame jumping when recording
to an external video device. He claims it and a bunch of other stuff is
fixed in version 2.0 (due out in july) Some highlights of version two
include the ability to work on 1024 X 1024 X 5 images in lo-res mode
with a way of scrolling the image around on the screen, Being able to
switch modes (lo-res, med-res, hi-res) with a menu selection and still
retain the image you are working on, rotatable ellipses, "low pass filtering"
of the image (basically a brush mode that provides a simple anti-aliasing
capability), runnable from the workbench. There were some more but I
don't remember them all. (This was two months ago after all) I certainly
am looking forward to it.
